Torch Viewing Position Alignment
The torch viewing position alignment procedure is used to set the plasma viewing
position of the spectrometer entrance optics for the highest signal intensity. See
Setting the Torch Viewing Position
Perform this procedure when:
•
the instrument is first installed or moved to a new location, or
•
the torch is removed or replaced, or
•
the plasma induction plates are replaced
(important)
Performance Checks
Several checks should be done periodically to check instrument performance. These
include the sodium bullet test to check the nebulizer argon flow, the Background
Equivalent Correction (BEC) test, and Coefficient of Variation (CV) test. These tests
are described in Chapter 6, Troubleshooting.
Cleaning the Sample Introduction System
See the following table for the recommended cleaning procedures for the sample
introduction system.
Table 5-1.
Recommended Cleaning Procedure
Daily cleaning
After analyzing aqueous solutions, flush with
deionized water, or 2% nitric acid, followed by
deionized water. After analyzing organic solutions,
flush using a clean solvent.
Torch
Injector
Spray Chamber
Soak in 5-20% nitric acid or aqua regia; use an
ultrasonic cleaner if available. For more detailed
information, see
Cleaning the Torch
later in this
chapter.
O-Rings
Clean with soap and water, rinse thoroughly.
GemTips for Cross-
Flow Nebulizer
Clean with soap and water, rinse thoroughly; or use a
2% solution of nitric acid.
